Taliban 1.0 And 2.0 In Afghanistan: Same Policies, Persistent Vision, Sharif Hozoori

Journal of Strategic Security

The Taliban emerged as a movement in 1994, toppled the government of the Mujahideen, and ruled Afghanistan from 1996 to 2001. They finally recaptured power in 2021 after the US withdrawal from the region. This paper refers to the first Taliban rule as Taliban 1.0 and their second as Taliban 2.0. Taliban 1.0 imposed draconian laws and regulations on women and minorities while harboring regional and international terrorist organizations. Later, the Taliban 2.0 followed its predecessor in policies regarding women, minorities, and sheltering terrorist organizations. Considering this background, this paper addresses whether Taliban 1.0 and 2.0 maintain the same policies …

Phosphorus: From The Origins Of Life To The Origin Of An Industry, Joshua Abbatiello

USF Tampa Graduate Theses and Dissertations

The element phosphorus is a key biogenic element that is often the limiting reagent for life. Phosphorus is quickly bound by metal divalent cations making it virtually insoluble and inert in water (forming the phosphate mineral apatite). Due to this, it becomes imperative to understand alternative pathways to increase biogenically available phosphorus in environments. To that end, this dissertation involved examining olivine as an alternative source of phosphorus to apatite, analyzing a novel grain of iron silicide found via lightning reduction in a fulgurite, and finally sought to understand the impact of phosphate mining through phosphogypsum stacks. Olivine is a …

Beyond The Gray Ghost: John S. Mosby And The Power Of Legend, Kevin R. Youngberg

USF Tampa Graduate Theses and Dissertations

Civil War generals are among the most celebrated figures of their time. In the post-Civil war era, many of these officers retreated to farms, and businesses and disappeared into obscurity. This was not the case with Colonel John Singleton Mosby, who quickly transformed into a figure whose legacy from the Civil war gave him a unique place in the American imagination as the legendary Gray Ghost of the Shenandoah Valley of Virginia. He lived until 1916, a remarkable fifty years filling those decades with a host of accomplishments in public service both at home and abroad. His legacy is complex, …

An Exploratory Analysis Of Automated Deception Detection For Mental Health Applications, Sayde Leya King

USF Tampa Graduate Theses and Dissertations

Deception in mental health settings can undermine therapeutic relationships, compromise treatment efficacy, and impact patient outcomes. Yet, research shows that mental health clinicians often perform no better than chance at detecting deceptive behavior in therapy. Automated deception detection, leveraging artificial intelligence (AI) and multimodal behavioral cues—such as eye gaze, body gestures, and facial expressions—offers a promising alternative. However, most existing research focuses on high-stakes legal contexts, limiting its applicability to mental health settings.

This dissertation addresses this gap by pursuing three key research objectives using a mixed-methods approach. First, we investigate mental health clinicians’ perspectives on AI-assisted deception detection through …

Digital Resistance And The Political Economy Of Authoritarian Decline And Economic Liberalization In Ethiopia, Anaol Dalle

USF Tampa Graduate Theses and Dissertations

This dissertation aims to examine the impact increased consumption of digital technologies, like social media and the internet, has on the stability and autonomy of low-capacity authoritarian countries. By using Ethiopia (2015-2021) as a case study, the dissertation argues that the sudden adoption and proliferation of digital platforms serves as an exogenous shock that pushes the state into a critical juncture that unravels institutional equilibria and transforms domestic incentive structures and institutions. This creates a power vacuum, which triggers a period of intense, and often violent, competition between elite groups, significantly destabilizing the state. In the absence of a cohesive …

Physical Activity And Functional Mobility In Adults With Hearing Loss: A Series Of Embedded Studies Within A 6-Month Clinical Trial With Hearing Aids, Sarah L. Bochat

USF Tampa Graduate Theses and Dissertations

Adults with hearing loss engage in low levels of physical activity and demonstrate poor performance on measures of functional mobility. The impact of hearing rehabilitation on these outcomes is not fully understood. Previous investigations were largely quantitative and focused on older adults ≥ 65 years of age who may respond differently to hearing intervention than relatively younger adults. They also tended to focus on exercise rather than global engagement in physical activities and did not report hours of hearing aid use, an important indicator of intervention success. One purpose of this dissertation was to determine the feasibility of collecting accelerometry-assessed …

Democracy, Expertise, And The Disinformation Problem, Richard Randall Frohock Iv

USF Tampa Graduate Theses and Dissertations

Experts are an essential part of our social epistemology. They grant us access to knowledge that would otherwise be inaccessible. Because of this, experts are also typically seen as invaluable political contributors. Without expert contributions, public policy risks being ill-informed and therefore incapable of addressing society’s needs. Recently, however, the extent to which expertise should inform public policy has come into question. Fueled largely by disinformation, there is a growing movement against traditional experts. Those within this movement argue that experts have overstepped their bounds and are working against the societies they are meant to be helping. Fearing that that …

Quantifying Adversary Military Forces’ Susceptibility To Cognitive Attacks, Bonnie Rushing, Cole Nelson, Shouhuai Xu, Christofer “Raven” O’Keefe, Olga Karpoyan

Military Cyber Affairs

This paper introduces a method to quantify international populations’ susceptibility to cyber cognitive attacks using press freedom and media trust metrics. We present the Cognitive Influence Calculator, a tool that estimates susceptibility (𝑆) based on Press Freedom Scores (PFS) and media trust levels. Findings show that while authoritarian regimes are harder to reach, successful cognitive attacks have greater impacts due to higher trust in state-controlled narratives. Using U.S. wargaming data and international trust metrics, we compute susceptibility scores for the U.S., Russia, China, Iran, and North Korea. Results show an inverse relationship between PFS and media susceptibility, with local/allied …

The Only Constant Is Change: The Role Of Genetic Diversification In Cancer And Beyond, Malgorzata Tyczynska Weh

USF Tampa Graduate Theses and Dissertations

Genetic diversification, the process by which genetic variation arises in a population, is fundamental to evolution by natural selection. Mutation, a central diversification process, fuels adaptation across species, including in cancer. Yet most new mutations are neutral or deleterious on cell fitness, raising the question of how mutation-driven adaptation persists. To explore this paradox, I developed a spatial agent-based model (ABM) in which population fitness emerges from individual cells acquiring mutations at varied rates and with diverse fitness effects. I evaluated model behavior across adaptive states, mutation rates, and distributions of fitness effects. The results show that high mutation rates …
